HYDRAULIC PUMP.

Specification of Letters Patent. Patented J an. 29, 1918.

Application filed Itovember 10, 1916. Serial No. 130,679.

I '0 all whom it may concern:

Be it known that I, WILLIAM H. SEELY, a citizen of the United States, residing at Pinson, in the county of Jefferson and State of Alabama, have invented new and useful Improvements in Hydraulic Pumps, of which the following is a specification.

This invention relates to hydraulic pumps.

The object of the invention is to provide a hydraulically operated pump, wherein power is obtained from a dam, the water passing through chambers containing alternately operated paddles, which paddles transfer their motion to a pump.

A further object of the invention is to provide a pump of this character which will lift the water to a great height by means of a slight fall of water from a dam.

lVith the above objects in view the invention consists of the following novel combination and arrangement of parts illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings;

Figure 1 is a side elevation of the improved pump;

Fig. 2 is a horizontal sectional view of the same taken on a line above the gate operating arm;

Fig. 3 is a vertical longitudinal sectional view taken on a line through one of the chambers;

Fig. 4 is a transverse sectional view show ing the connectionsbetween the swinging paddles and the rocker arm;

Fig. 5 is a vertical longitudinal sectional view taken through the pump cylinders.

Fig. 6 is a detailed vertical sectional view taken through one of the pump cylinders, and the common outlet chamber; and

Fig. 7 is a detailed perspective view of the rocker arm and the pivot bar for operating the swinging gate.

In the drawings wherein like characters denote corresponding parts, the casing is shown at 1. This casing is of preferably a rectangular shape, and is provided with a semi-circular top 2 hinged thereto by means of hinges 3. This enables ready access to be had to the interior of the casing, which is divided by a central partition 4 into chambers 5 and 6. These chambers are provided with a common inlet opening 7 in which operates a swinging gate 8. This gate is hinged to the partition 4 and is automatically operated to alternately open and by the partition 4:. An upright member 17 provided with a bifurcation 18 is carried by the lever 15, the said bifurcation being adapted to loosely receive one end of a rightangled portion 19 of a pivot bar 20. This bar is pivoted at 21 upon the partition 4 so as to have a horizontal-movement thereon, and is provided at one end with a loop 22. An arm 23 positively secured to the gate 8, has its free end passingthrough the loop 22.

The paddle 10 carries at its end opposite the hinge 11, an upright rod 25. This rod is pivotally mounted upon the paddle 10 and passes through a guide 26 carried by the casing 1, and extends forward through a suitable slot 27 in the hinged top. An extended portion 28 of the rod 25 has a link connection 29 with a rocking lever 30. The lever 30 is pivoted at 31 upon an upright 32 mounted upon the casing 33 containing the pump cylinders 34. The usual suckers 35 are adapted to operate within the cylinders and carry sucker rods 36 connected with the rocker arm 30 by suitable links 37. Inlet valves 38 are provided within the pump cylinders, the said valves being of any preferred construction. Outlet ports 39 connect with a common chamber 39 said ports 39 being provided with suitable valves 40. The valves shown are of the flap type and are held normally in position by means of a spring 41. An outlet port 42 is provided for the chamber 39.

The operation of the pump is as follows: Water is pumped through the inlet 7 into either the chamber 5 or 6, the weight of the Water pressing down one of the paddles 9 or 10 and operating the rocker arm 15. This arm through connection with the lever 20 will swing the gate 8 first to one side and the other of the inlet 7 causing the alternate operation of paddles 9 and 10. Through the connection '25 of the paddles 10 with the rocker arm of the pump the pump or sucker rods are caused to operate within their cylinders and force the Water through the outlet 42.

From the foregoing description it will be seen thatthe invention provides a simple,

economical and efiicient pump.

Various changes in the form, proportions and minor details of construction may be made as will properly come within the scope of the appended claims.

Having described the invention What I desire to claim, is:-

1. A hydraulic motor comprising a pair of vertically swinging paddles, horizontally swinging means for controlling the alternate movement of said paddles, and means for transferring the motion from said paddles to a pump.

2. A hydraulic motor comprising a pair of swinging paddles, a partition separating said paddles, a pivoted end for said partition, means operated by said paddles for controlling the movement of the pivoted end, and means for transferring the motion from said paddles to a pump.

8. A hydraulic motor comprising a pair of swinging paddles, a partition separating said paddles, a pivoted element for controlling the operation of the paddles, a transverse rocking lever operated by said paddles, a bifurcated member carried by said lever, a pivoted arm engaging said bifurcated member and said swinging partition and means fortransferring the motion from said paddles to a pump.

4. A hydraulic motor comprising a casing, chambers provided in said casing, swinging paddles in said chambers, inlets for said chambers, a gate alternately opening and closing the inlets, a transverse rocking lever operated by said paddles, a pivoted arm engaging said rocking lever, a sliding connection between said lever and said gate and means for transferring the motion from said paddles to a pump.

5. A hydraulic pump comprising a casing, a horizontally movable element mounted therein, vertically movable members also mounted. within said casing, means whereby the motion of the vertically movable members is transferred to the horizontally movable element, a pump and means whereby the vertically movable members will operate said pump.

6. A hydraulic pump comprising a casing, said casing being divided into separate chambers, pivoted members in each of said chambers, means located at the entrance of said chambers for controlling the alternate operation of said members, a pump and means whereby the motion of the pivoted members is caused to operate the pump.

In testimony whereof I aflix my signature.
